We visited Ripley at around 11am on Saturday - not very crowded. We found that it was $3 cheaper per ticket to order through online. So we booked online and scanned online tickets from the lobby and went in. They have a lot of interesting situations and features, and many exhibits that you can touch and experience with your hands. All members of our team - from grandparents to children as young as 6 - love this place. It's a good place, it probably takes about2-3 hours.
